DOUGH-MOLDING MACHINE.

Application filed. August 31, 1925. Serial No. 53,702.

To all whom it may concern:

Be it known that 1, JOHN Enwinu) Poinroiv, a British subject, residingat Hythe Road, VVillesden Junction, London, NlV. 10, England, haveinvented certain new and useful Improvements Relating to Dough-MoldingMachines, of which the following is a specification.

This invention relates to machines for the molding of dough for breadmaking, particularly of the type known as preliminary molding or handingup machines wherein the dough portions from a divider are, prior toadmission' to the prover, subjected to a rolling and screw like motionby means of a rotating conical table with which is arranged a spirallydisposed fixed trough or conduit.

The invention has for its object to tate the melding of the whole ofthedough portions delivered on each discharge of the division boxes of thedivider and the subsequent placing of the same on the prover trays orshelves.

The invention comprises the combination with the conical rotating tableor like element of the handing up or molding machine, of a plurality ofspirally disposed troughs o1 conduits and the arrangement of the samewith respect to a multiple box divider and a prover to simultaneouslyreceive the whole of the dough portions on each discharge of the dividerboxes, and similarly deposit them after the molding operation upon ashelf or tray of the prover.

Referring to the accompanying sheet of explanatory drawings Figure 1 isa sectional elevation, Figure 2. a plan, and Figure 3 an end elevationillustrating a dough molding machine or molder, constructed inaccordance with this invention.

Figure 4c is a diagrammatic plan showing the position ofthe said molderrelatively to the dough dividing machine, or divider, and the provingmachine, or prover.

The same reference letters in the dili'erent views indicate the same orsimilar parts.

In the illustrated application of the invention to an automatic breadmaking plant comprising a dough divider a having a pluality of divisionboxes 6 and a prover c with trays or shelves carried by eithercontinuous or intermittently moving endless chains d, the lrander' np orpreliminary facilimolder c has a plurality of troughs or conduits fcorresponding with the said division boxes. Thus for use with a fourboxdivider the hander up has four troughs or conduits spirally disposed asshown with respect to the cone or table The axis of the said cone ortable is preferably inclined. with respect to the base of the machineand it is rotated through gearing driven from the divider or in anyother convenient manner. The gearing shownin the illustration comprisesthe counter-shaft h. with the chain wheels 1', driven from the divider,and bevel gears j, spindle 7c, and pinion Z engaging the wheel orannulus m which is secured to cone or table 9.

The troughs are supported in any convenient manner. Thus, at the oneside or end the troughs are attached to the bracket or bridge likemember 0 and the other side or end to the post or like support 72.

. The admission ends of the troughs 7 are suitably arranged with respectto the discharge position of the division boxes Z) to receive the doughportions immediately on discharge from such boxes. A shoot as 9 may beemployed to facilitate the feeding of the bottom trough. To providesubstantial uniformity in the length of the respective troughs and thusin the extent oithe molding action on the dough pieces passingtherethrough, the troughs nearer to the centre 011 the cone 9 extend, asshown, through a greater portion of a circle than. the troughs moreremote from the centre. The discharge endsof the troughs will thus be atvarying distances from the centre of the cone but extension pieces ordelivery arms r of vary ing length are employed so that the molded doughportions discharge in alignment into a hopper s or the like arranged todirect the said portions on to the prover trays or shelves. The saidhopper or the like has a retaining slide or flaps as t, 6 arranged foroperation by a timing cam u associated with a lever or link system andworking in unison with the prover to ensure that the dough pieces passout from thehopper only when a prover sheli or tray is in position toreceive them. The said link s stem comprises shafts o and o having therespective flaps z", 25, secured thereto. The shaft 12 has the lever 1.0secured to one end of it, said lever abutting on cam u, and the shortlever 00 Having thus described my invention What I claim as new anddesire ters Patent is z 1. In dough molding machines, the combinationwith a conical rotating table, of means whereby the movement of saidtable etiects the simultaneous melding of the Whole of the doughportions received from each discharge of a multiple box dough dividerand delivers said molded portions on to a dough prover, saidmeans'comprising a plurality of spirally disposed troughs fixed abovebut adjacent the said table and torming conduits'between the saiddivider and prover.

2. In dough molding machines, the combination with a conical rotatingtable, of means whereby the movement of said table effects thesimultaneous molding ot the whole or the dough portions received fromeach discharge ot a multiple box dough divider and delivers said moldedportions on to secure by Letto a dough prover, said means con'iprising aplurality of spirally disposed troughs fixed above but ad acent the saidtable, and delivery arm's between the outlet ends of said troughs andthe said prover.

3. In dough moldin'gmachines operating in association with a doughdivider and a dough prover, the combination comprising a conicalrotatingtable, a plurality of spirally disposedtronghs of approximatelyuniform length nrced respectively over and under each other above but adacent the said table and in position to receive at one end the Whole ofthe dough portions from each discharge of a multiple box dough divider,and delivery arms between the opposite ends or" the said troughs and thedough prover, the said arms being of varyinglength to accommodate thevarying distances between the respective troughs and the said prover.

st. In dough molding machines operating in association with a doughdivider and a dough prover, the combination comprising a conicalrotating table, a plurality of spirally disposed troughs fixedrespectively over and under each other above but adjacent the said tablend in position to receive at oneend the Whole of the dough portions fromeach discharge of a multiple box dough divider, deliveryarms at theopposite ends of the trough, and a hopper between the outlet ends ofsaid arms and. the dough prover.
